  1. I don't know if the currently available detailed implementation of QI theory is correct but the idea of inertia being the imporatant thing seems totally plausible. The only big problem I see with this idea is E=mc² where I fail to see any inertia but otherwise mass could be defined by its inertia – inertia is basically the only thing to practically identify high mass object from low mass object if you're not on Earth.

  2. Great video! The only major problem you missed is the cost and weight of the H2 tanks. Even for airplanes, battery power starts to seem better than H2. In bigger picture, the poor efficiency for H2 production and use makes it better than diesel in best case. Hydrogen could be the least worst option if we didn't have anything better. But we do.

  3. Using aluminium air batteries packaged in shipping containers to power ships that transfer similar sized shipping containers is actually a really good idea. The infrastructure needed to handle those containers is already installed and you could collect used battery containers in ports and transmit those with one full ship to recycling once done. In addition, since putting e.g. 10 extra containers in a large ship is no problem you wouldn't need to have a recycling station at every port so logistics would be pretty easy to solve. On the other hand, using those for cars sounds a bit more problematic. I would assume that recharging would be much better option overall for cars because you can cheaply build the infrastructure over time. EV cars can already be used today and the more charging locations we get, the lesser problem the recharging will be. I'd expect to see overhead charging cables on highways in the future, a bit similar to ones used to power trains today. That would allow you to recharge batteries while driving the long runs and use fully charged batteries in the cities.

  4. If somebody really believes in death penalty, it should be executed by introducing enough carbon dioxide or carbon monoxide in the the air that the sentenced is breathing. Either will force you to lose consciousness before killing you. Carbon monoxide might cause major headache, though.
